We used Australian Visa Lawyer to manage my partner visa. The migration agent handled our case is professional, kind and responsive. Whenever we had a query she was always quick to answer it with related information for us and managed to reassure us when we were stressed. She even called us on a public holiday to inform us the visa had been granted. She made the whole process many times easier than it would have been if we did it alone.
Highly recommended if you want to take the stress out of your visa application and looking for the best migration agent in Sydney!
